ICDAS Generic Model Creation generate BIM-model in Revit. In many other ICDAS models the word BIM-model is known as ‘Geometry model’ which strongly refer to the 3D-geometry of the model. However, a BIM-model is not only about the 3D-geometry, but it contains both graphical and non-graphical information in a Common Data Environment e.g. material, volume, identity added to individual family properties and so on. Benefits of Revit Bridge BIM model are many, below are the most practical features / guides highlighted:

›    Revit displays all by "view" with adjustable 3D deep "Far Clip Offset". One can easily generate an arbitrary view from

    the 3D model for dimensions, elevations and notations. With e.g. a view A on a 3D object A you can measure

    dimensions/elevations of the cross section at both beginning and end of the object A when "Far Clip Offset" is drawn

    to the object length. I.e. "2D cut" is when you drag the "Far Clip Offset" only a few mm over an object cross section.

›    With just one click, Revit project file * .rvt is sent directly to Revit LIVE cloud services in *.lvmd format from which

    the user can give access to all involved project partners, including on site with wireless internet connection.

›    It's just a click in Revit LIVE for Virtual Reality where all the details will be visualized as they really are (VIVE HTV

    headsets required).

›    Revit project file * .rvt stores all 3D section files (family files *.rfa) in one project file. Here you can double-click on

    any section to open its family file for editing, development or measurement and load that section back to project file

    (intelligent model-based technology).

›    Storing bridges in Revit BIM models will make it easy and possible to develop, deploy, share and reuse digital data for

    the rest of the bridge's lifecycle. For large building or infrastructural construction, 3D BIM model is also the starting

    input for 4D Time model (interconnection between 3D BIM model and time schedule), 5D Economy management model

    and 6D Operation and Maintenance model.

All ICDAS Revit models are BIM-models.

Bridges Condition in Denmark

The Danish Road Directorate has defined condition ratings for exiting bridges in Denmark. They are from 0 (best) to 5 (worst) as described below (Tilstandskarakterer)

0: Absolutely insignificant signs of degradation

1: Only minor signs of degradation

2: The occurring damage is at a low level of development. Repair should be performed occasionally.

3. The damage has evolved and remediation within a few years is expected to be necessary.

4. The element is highly degraded and repair should take place in the near future.

5. The element is completely degraded and repair is required immediately

The tables below shows the distribution of the bridges in condition ratings 0-5 for the individual kommune in Denmark (local government). There are 69 of 98 kommunes participated in the tables (BroIndeks 2015). The 69 kommunes are raking after maximum number of bridges (in all of ratings 0-5). 

Bridges with condition rating 2 and over require repair. There are 2389 of the total 6247 bridges in the 69 kommunes have this rating and therefore require repair (1671+574+128+16).
